[checkmk-commits] 3737 FIX Fixed slow activation of changes due to loss of IP address cache

Module: check_mk Branch: master Commit: 23100edfa43290b706e6b4f67e51651d58061797 URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=23100edfa43290… Author: Mathias Kettner &lt;mk(a)mathias-kettner.de&gt; Date: Mon Sep 26 23:25:30 2016 +0200 3737 FIX Fixed slow activation of changes due to loss of IP address cache In some situations Check_MK would loose the cached IP addresses in <tt>var/check_mk/ipaddresses.cache</tt>. The results in the next activation of changes being very slow - depending on your DNS. The problem seems to happen (especially) if you have activated periodic service discovery with automatic activation of changes. This has been fixed. --- .werks/3737 | 16 ++++++++++++++++ ChangeLog | 1 + modules/check_mk.py | 1 - 3 files changed, 17 insertions(+), 1 deletion(-) diff --git a/.werks/3737 b/.werks/3737 new file mode 100644 index 0000000..1eb7161 --- /dev/null +++ b/.werks/3737 @@ -0,0 +1,16 @@ +Title: Fixed slow activation of changes due to loss of IP address cache +Level: 2 +Component: core +Class: fix +Compatible: compat +State: unknown +Version: 1.4.0i1 +Date: 1474925029 + +In some situations Check_MK would loose the cached IP addresses +in <tt>var/check_mk/ipaddresses.cache</tt>.
